Summary from Kohesio (English machine translation by the source): Most modern optoelectronic devices are made of different types of materials. In this type of joints, so-called conductivity and valent strip breaks occur. Thanks to them, quantum pits are formed and they form potential barriers for semiconductor chargers. Therefore, knowledge of these sizes is very important when designing semiconductor devices. The aim of this project is to develop a methodology that can determine the burst energy of the conductivity at the junction of two different semiconductors. Since THz impulse generation is heavily influenced by the semiconductor belt structure, various barriers and electric fields generated by the two-way interface, it can be used effectively for the research of semiconductors and their derivatives. This work will use the THz excitation spectroscopy method for the determination of the above mentioned amounts. Initially, the energy of the side valley of the conduction band and the conductivity band break in the THz excitation spectrum will be determined for the conduction of the conductivity band in high-thickness semiconductor layers. As the electrical fields in the sample are likely to significantly influence the results of the experiment, samples will be prepared at the next stage where the surface and heterosandure electric fields are minimal or their influence on the experimental results is small. This will lead to the next, last step, which will determine the breakage of the conductivity in the heterosandura of the substances to be tested and how this value depends on the amount of additional atoms.
